2,2,3,3,4,4,5,5,5-Nonafluoropentyl difluoromethylether CAS 1661005-79-3

Description

Owing to a hydroxyl group, an ether linkage, fluorine substitution, 2,2,3,3,4,4,5,5,5-Nonafluoropentyl difluoromethylether is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 300.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

2,2,3,3,4,4,5,5,5-Nonafluoropentyl difluoromethylether (CAS 1661005-79-3), molecular formula C6H3F11O and molecular weight 300.07 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 2,2,3,3,4,4,5,5,5-Nonafluoropentyl difluoromethylether meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
